Redmine

Hi all,
i'm giving a shot to redmine with the following env:

Java 1.6.0_07
jruby 1.1.4 (ruby 1.8.6 patchlevel 114)
redmine trunk (svn checkout)
actionmailer (2.1.1)
actionpack (2.1.1)
activerecord (2.1.1)
activerecord-jdbc-adapter (0.8.2)
activerecord-jdbcmysql-adapter (0.8.2)
activeresource (2.1.1)
activesupport (2.1.1)
jdbc-mysql (5.0.4)
rails (2.1.1)
rake (0.8.1)
rspec (1.1.4)
sources (0.0.1)
MYSql 5.0.67
Win XP pro Sp 3

I got the WEBrick access to redmine up and running in minutes and everything was ok until i configured and tried to access my first CVS repo.

I'll be short, everything gets stuck after changesets download. I tried also the offline Repository.fetch_changesets as per advice in the doc but to no avail. Also it hangs.
Monitoring port 2401 of CVS server i see the entire log is transferred in few tenth of seconds, (is a sandbox repo with very very little activity), after which nothing else happens.
No messages, no errors, no cpu activity, no network activity, db remains empty, the application is hanged and most of times won't even react to ctrl-c and must be brutally killed.

In one of the attempts i tried to wait a couple of hours, but after the few seconds of initial activity, during which a bunch of
trunk/lib/redmine/scm/adapters/cvs_adapter.rb:315 warning: instance variable @branchid not initialized
messages are written, nothing else happened. I red that first access is slow but even two hours to process a log that contains at most a few hundreds commits is a bit too much overkill :)

Does anybody has experience of a similar env or has advice on how to proceed/debug this thing?

Thanks, Gabriele
